SPECIFICATION forming part of Letters Patent No. 298,605, dated-May 13, 1884:.

Application filed May 19, 1883. (No model.)

To all whom, it may concern:

Be it known that I, WILLIAM Mrcenrr, a citizen of the United States of America, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Stoves, Ranges, Furnaces, or other Heating Medium, of which the following is a specificaation, reference being had therein to the accompanying drawings.

This invention consists in certain improvements, as will be hereinafter described and claimed, in the construction and arrangement of a series of ilues, dampers, ne., whereby the heat from a stove, range, furnace, or other heating medium may -be conveyed to and retained for any desired period in any desired position of contact with an oven, boiler, &c.

In the drawings, Figure l represents a perspective view of a part of a cook-stove having my improvements applied thereto, the top of the stove and the bottom plate of the oven being removed. Fig. 2 represents a vertical transverse section on the line 2 2 of Fig. l.

It is the design of my improvements, by means of damper-s and fines, to convey the products of combustion from stoves, ranges, furnaces, 8vo., or heat from any other source of supply, to a chamber or compartment at that point of the structure or article which it is desired to heat, and by means of peculiarlyconstructed ilues or division-plates to check and regulate the flow of the heated air and retain the same at any desired part of the structure, and thus, with the employment of much less fuel than is ordinarily employed, and the utilization. of the utmost possible amount of the heat gcnerated,to heat the oven, boiler, or other article more quickly and effectively than where the heat is allowed to pass unrestrainedly from the furnace to the oven and thence to the exit-flue.

In the drawings hereto annexed I have shown my invention as applied to an ordinary cooking-stove. It may, hwever, be with equal facility applied to ranges or furnaces generally, so as to convey the heated air to and retain it in the desired position until the maximum of the heat is extracted from the heated airE A. represents an ordinary cook-stove.

B represents a damper hinged at the rear of the stove above the furnace. This damper p has attached thereto the rear end of an actuating-rod, C, which at its front end is notched or serrated, as shown at c, such serrated or notched portionworking in a slot, I), formed in the front wall of the stove. Vhen it is desired to retain the damper B in closed position, the rod C is drawn forward to its fullest extent, and thel rearmost notch dropped into engagement with the slotted wall. This will prevent the exit of any of the products of oombustion directly from the top of the furnace and compel the same to pass directly across the top ofthe oven to the vertical side flue, D. The volume ofthe heated air or products of combustion passing to the flue D may be regulated by raising the front end of the rod C from engagem ent with the slot Z), and pushing said rod inward the desired distance, and then placing the notched end in engagement with the slot b. The recess or chamber E, beneath the bottom plate, F, of the oven G, is divided by means of strips or (.lividing-platcs H I J, which I denominate retainers7 into four reservoirs, l 2 3 4. rlhe bottom plate,F, of the oven is formed separately, and is placed in position, as shown in Fig. 2, by passing the same through the ovendoor, and then sliding it down until it rests upon the top edges ofthe strips H I J. Vhile thus resting upon the strips the bottom plate forms each reservoir into a close chamber, eX- cept at the vent-openings 5 6,which are formed in the upper edges of the several strips II I J by cutting down the division-strips :at one end for about one-third of their depth. Access can be readily had to thev iiucs or reservoirs by simply raising the bottom plate, F, of the oven. rlhe rear wall of the oven is provided with an exit, c, for the utilized products of combustion. This exit is guarded by a hinged damper, IWI, which is connected with and operated by a rod, N, of similar construction to the rod C. The heated air and products of combustion pass over the top of the oven to and down the flue D, which, at its bottom, communicates directly with the caloric-reservoirs l 2. The heated air passing down the front part of the vertical iiue l) enters the reservoir 1 and passes along the same to and through the vent 5 to the reservoir 8. The

IOO

heated air passing down the rear portion of the vertical ilue D enters the reservoir 2 and passes along the same to and through the vent 6 to the reservoir et. XVhen the damper in the rear wall ofthe oven is closed, the heated air passing down the vertical Hue will fill the several reservoirs 1 2 3 4, and remain there as long as said damper remains closed.

At the rear ends of the reservoirs 3 and 4, and forward of the damper, are interceptors 7 8, which serve to partially intercept the air in its passage to the damper, but are, as shown, of slightly-less height than the retainers, to admit of the passage of the air to the damper M. As the hot air passes out through the bottom of the vertical iiue, it will inipinge against the sides of the strips or retainers II I, and be forced upward thereby against and into contact with the bottom plate of the oven, and similarly as said hot air flows through the vents 5 and G it .will be projected upward against the bottom plate, and as the air having an excess of caloric is lighter than the cooler air the hotter part of the air will be constantly in contact with the bottoni plate ofthe oven. By opening the damper at the rear of the oven to a greater or less extent,a constant current of warm air of more or less intensity and volume will be caused to travel along the bottom plate. Vith this system of hot-air reservoirs under the oven, they being continually charged full of caloric air, the new product, being always the lightest, is always nppermost in passing through the reservoirs, thereby forcing the hottest part ofthe caloric current up against and along the bottom of the oven. By means of these interceptors and retainers the heat can be distributed and-retained whenever wanted, and the richest part of the caloric kept immediately under the oven where it is wanted.

I am aware that cook-stoves have been'constructed with the danipers land fines for the purpose of conveying heated air and the products of combustion from the fire across the top ofthe oven, and to a chamber or recess beneath the oven; and I ani also aware thatV such chamber or recess beneath the oven has been provided with a series of division-plates for the purpose of causing the heated air and products of combustion to circulate beneath the oven, and such features I do not broadly claim.

Having thus described my invention,what I claim therein `is- 1. A cook-stove or analogous article provided at its upper portion with a damper to regulate the passage of hot air or products of combustion from the source of supply to the part to be heated, a vertical side flue to convey said heating medium to the desired position, a hot-air chamber having a series of strips or dividing-plates, each having a vent opening at the top edge of one end, and a damper for the purpose of releasing the spent heated air, substantially as and for the purpose set forth. f

2. .In a stove, furnace, or equivalent heating device, the combination, with a suitable flue connected at one end with the source of heat-supply, and at the other end with a hotair reservoir, of a hot-air reservoir having a series ofdividing-strips, each having at one end a vent opening or notch, a plate adapted to rest against the upper edges of said dividingstrips, and a damper and vent opening, through which the heated air is discharged after use, substantially as set forth.

3. A cook-stove or analogous article having damper B and notched rod G above the furnace, vertical flue D, caloric-reservoirs l 2 3 4, and damper M, and notched rod N, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
